Question

if the momentum of the NASA space suttle as it leaves the atmosphere is 3.75 x 108 kg•m/s its mass is 75000kg, what is its speed

Answer 1

Answer:

momentum=mass*speed...speed=momentum/mass

=3.75*10⁸/75000=5000m/s

Answer 2

According to the question the momentum of the NASA space suttle as it leaves the atmosphere is 3.75 x 108 kg•m/s, its mass is 75000kg, now we have to determine its speed or velocity ,

we all know that velocity= momentum/mass

•Here according to the question the momentum is 3.75× 108 kg.m/s

and the mass is 75000kg

so the velocity or speed would be (3.75 x 108)/ 75000 = 5.4 × 10^-3 m/s
